In the presence of catalytic amounts of Pd(PPh3)4, 3,4-benzo-1,1,2,2-tetraethyl-1,2-germacyclobut-3-ene (1) readily undergoes the reversible σ-bond metathesis to give a dimer, 1,2,5,6-dibenzo-3,4,7,8-tetragermacycloocta-1,5-diene (6) below 100°C. H

The thermolysis of 1,1-dimethyl-1-germacyclohepta2,4,6-triene led to the formation of benzene and dimethylgermylene, as expected. The activation energy and thermodynamic data for the germylene extrusion reaction were determined to be E a = 21.2 ± 0.

Photolysis of phenylpentamethyldigermane afforded hydrogermanes and digermanes, as main products. These are derived from two germyl radicals generated by photo-induced homolysis of the germanium–germanium bond. Dimethylgermylene is shown to be evol
